Well, probably no one has (asked) lately, but
I received four packs yesterday, the two "Woodland Indians" and two "Braddock's Defeat" (British & French). I set them out for comparison with the numerous Suren and Redoubt 18thC/FIW that I have.
The three lines are virtually identical in height. An exception being an Indian (BM) who would be ca. 6'2" or so. But he is believably proportioned to be, simply, a tallish fellow, not some muscle-bound heroic type.
He has his musket in the crook of his arm and is obviously "directing things" so the figure, and its extra height, fit his presumed role of leader quite well.
The BM are slightly "leaner" than Redoubt and, for the most part, the anatomy and naturalness of their poses overall are a bit better. Both these lines would very easily blend into the same units (the Indians and irregulars at least), they are so close in style and "heft". Individual taste would have to dictate mixing the Euopean troops from the two.
For any graybeards here who are fortunate enough to have original Surens cast in the late 60s/early 70s (not the rather "ethereal ETs" of recent decades) these also are decidedly compatible with Redoubt and Blue Moon being only _very_ slightly thinner.
I have no NoAm Indians from Perry or Conquest FIW to compare, but other the periods I have from Perrys are quite noticeably smaller in general; again subject to individual taste I suppose.
I am quite pleased with the three lines as larger 28s and do hope that Blue Moon will have the time and inspiration to produce a comprehensive FIW line as was mentioned here last month by a BM(?) representative.
